The first time I applied for 1 year extension, I applied based on marriage. The next year I switched to retirement as the paperwork is much less and I easily met the monthly income figure on my pension.
Sorry buddy, but the OP asked about a specific visa. If they had asked about buying a ford sierra, would you have replied with a listing of a ford escort ????
I am guessing then that the work around here would be simply to arrive on an SETV and then change that into a non-imm O with the correct funds/paperwork.
